Abstract: 1,239,410. Integrated circuits. GENERAL ELECTRIC CO. 12 Aug., 1968 [11 Aug., 1967], No. 38540/68. Heading H1K. [Also in Division H3] An electromechanical filter which is made according to the methods disclosed in Specification 1,238,035 comprises a U-shaped cantilever resonator 12 of semi-conductor material, e.g. silicon, extending into a cavity 11 in a silicon body 10. As shown in Fig. 1 the body 10 and resonator 12 are integral but according to a modification (Fig. 2, not shown) the body 10 is ceramic and the silicon resonator 12 is bonded to the body at the ends of the arms 13, 14. The resonator 12 is coated with an insulation layer 16, e.g. silicon dioxide, and two U-shaped metallic strips 17, 18 are overlaid on the layer. The filter is situated in a constant magnetic field indicated by the arrows, the A.C. driving source 27 being connected to terminals 22 of the strip 17 whereby the current through the part 19 of the strip interacts with the magnetic field and the resonator 12 is driven at the frequency of the source 27. The Q of the filter may be varied by adjusting a resistor 33 connected between terminals 23 of the strip 18. To lower the Q value the value of the resistor 33 is decreased so that the voltage generated in the part 20 of the strip 18 causes a greater current to flow through the resistor circuit, this current serving to damp the resonator 12 and produce a less sharply tuned filter. The resistor 33 may be replaced by a field-effect transistor (Fig. 4, not shown). The filter output is obtained from a U-shaped piezo-resistive region 24 diffused into the resonator arm 14. If the resonator 12 is of P- type conductivity, region 24 is of N-type, the PN junction being reverse-biased by a D.C. source 36. The terminals 25 of the region 24 are connected by a circuit including a D.C. source 28 and resistor 30, the variation of the resistance of the region 24 due to the strain in the resonator being detected at an output terminal 31. A bandpass filter may be formed by connecting, electrically, a plurality of the filters in cascade (Fig. 3, not shown).

Abstract: 1,251,896. Bobbin hangers. NANIWA KIKAI KOGYO K.K. 29 Jan., 1969 [2 Feb., 1968], No. 502269. Heading D1J. The bobbin hanger shown in Fig. 3 carries a bobbin 62. When the bobbin 61 is empty it is raised manually to lift a slider 60 and therewith a rod 42 carrying a lower toothed clutch 32. The clutch 32 is free to rotate about the axis of the rod 42. The crests of the teeth of the lower clutch 32 are initially in substantial alignment with the crests of the teeth on an upper fixed clutch 28, Fig. 1. The bobbin 62 is raised until the teeth on the lower clutch 32 mesh fully with the teeth of the upper clutch 28, this meshing action causing the lower clutch 32 to rotate through half a tooth pitch. The clutch 32 carries toothed tails 33 that are lifted upwardly with the clutch 32 and rotate therewith to position the toothed tails 33 above circumferentially spaced teeth 36 within the bore 35 of the body 26. The upward movement of the slider 60 also causes bobbin supporting wings 47, 48 on the rod 42 to be retracted into the bobbin hanger. When the bobbin is lowered the rod 42 and lower clutch 32 descend until the toothed tails 33 engage and mesh with the circumferentially spaced teeth 36 in the bore 35, such meshing causing a further rotation of the clutch 32 through half a tooth pitch. The descent of the rod 42 is not sufficient, due to engagement of the tails 33 with the teeth 36, to permit the wings 47, 48 to project out of the bobbin holder. With the wings 47, 48 maintained in their retracted state the empty bobbin 62 can now be lowered off the holder. When a fresh bobbin is pushed upwardly onto the holder it causes the slider 60, and therewith the clutch 32, to rise and lift the tails 33 out of engagement with the teeth 36. Continued upward movement of the fresh bobbin causes eventual meshing of the teeth of the clutches 28, 32 and therewith a further rotation of the clutch 32 through half a tooth pitch. This causes the tails 33 to be moved out of alignment with the teeth 36 so that when the fresh bobbin is lowered the tails 33 can move down between the teeth 36 and the rod 42 can descend to a setting in which the wings 47, 48 move out of the holder to their bobbin supporting position.

Abstract: 1,258,562. Marine sound source. SEISMOGRAPH SERVICE (ENGLAND) Ltd. 3 Jan., 1969 [3 Jan., 1968], No. 388/68. Heading H4D. A sound source 3 for generating underwater acoustic pulses comprises an open-ended pipe which is moved through the water and which is provided at at least its leading end with a velocity transformer 7 so that water entering the velocity transformer flows along the pipe at a speed, relative to the pipe, which is greater than the speed of the source through the water, and further comprises cut-off means 5 for suddenly interrupting the flow of water along the pipe to produce an acoustic pulse by the " water-hammer " effect. One or more sources may be attached to a depressor 2 or to a pontoon for towing behind survey vessel 1, or the sources may be built into or fixed to the survey vessel. Velocity transformers 7, 8 are conical or exponentially tapered funnels. The cut-off means 5 is remotely controlled electrically, hydraulically or pneumatically from vessel 1 and may take the form of (a) a pair of apertured plates, one of which is moved to cover the apertures in the other, (b) a valve of the flapper or butterfly type, whose closure may be assisted by the water flow, or (c) a device for injecting high pressure air into the pipe against the water flow. If the pipe is rigid, closure of the cut-off means 5 results in a pressure pulse travelling back along pipe section 4 and a rarefaction pulse travelling along pipe section 6. Funnel 7 then acts as an acoustic horn for radiating the pressure pulse without unwanted reflection in the funnel. The rarefaction pulse may be broadened and attenuated by using a pipe section 6 and funnel 8 of appropriate dimensions and design, or it may be allowed to interfere with the pressure pulse from funnel 7 to give the sound source a directional characteristic. If the pipe is made compliant the acoustic radiation will be mainly from the pipe instead of from the funnels 7, 8. To this end the pipe may be constructed as (a) a perforated steel tube with an elastomeric outer sheath (e.g. of synthetic rubber), or (b) a tube of rubber reinforced by, e.g., a helical wire. The pipe compliance may be varied along the pipe (being lowest at the leading end) by varying the sizes and spacings of the perforations in construction (a) or by varying the pitch of the helix in construction (b). In a modified source for reducing inertial mechanical stress in the source and towing system when the water flow is stopped by the cut-off means 5, the pipe is provided with two opposed inlet branches such that the water flow directions in the two branches are respectively in and against the direction of travel of the source.

The container sits in heat transfer relationship within a cavity 14 of a metal block 12 of similar cross-section and which is heated and cooled by means controlled by a device to maintain the block at a predetermined temperature. A cooling fluid, e.g. liquid nitrogen, is passed through a space 19 formed between the walls 15, 18 of the block via pipes 10, 11 and the wall 15 has heating resistors 16 embedded therein, the action of which is limited to the central portion of the block by heat insulating material. Embedded in the walls of the box 1 are sealed portholes 5 registering both with holes 21 in plates 20 screwed to each side of the block and also with holes 41 formed in quartz discs 42 in the walls of the container 37. As a result the sample may be centred with respect to a light beam axis passing through the registering apertures from the measuring apparatus. The temperature control device comprises a probe mounted on the block and arranged to produce an output signal which is proportional to the block temperature and which is compared with a reference signal from a generator to actuate the power supply circuit to the resistors 16 or a valve 31, 33, 34 controlling flow of liquid nitrogen from a tank 26 to the space 19. An expansion chamber formed by a funnel 39 closed by a plug 40 is provided for the sample in the container 37.

Abstract: 1314008 Feeding tobacco MOLINS MACHINE CO Ltd 1 May 1970 [2 May 1969] 22564/69 Heading A2C A method of making cigarettes in which tobacco is showered on to a moving band includes the steps of extracting tobacco shorts before showering, and feeding the shorts by means of a vibrating tray towards the shower as a stream which is narrower than the stream fed to the shower, the tray having a substantially horizontal first section, and a downwardly inclined second section. An apparatus for carrying out the method comprises a carded drum 11 rotating anti-clockwise to convey a carpet of tobacco from a hopper 10 to a picker roll 14 which transfers the tobacco to a ramp 15 along which the tobacco passes, assisted by a spiked roller 16, to a suction drum 17 which delivers it to a chimney 18, 19 at the upper end of which passes a suction band. The tobacco is carried upwardly to the band by an induced air flow through a scroll 22, a duct defined by walls 38, 39, and a perforated block 21, and through a small additional air inlet 23. Heavy particles are rejected down a ramp 20. A spiked or dimpled drum 13, which helps to compact the tobacco on the carded drum 11, carries any shorts in the bottom of the hopper past a scraper 13A to a screw conveyor 25 which conveys the shorts to one end of a trough 24 where they fall into a tray 27 carried by flexible plates 28, 29 and vibrated by an eccentric 32 so that the shorts are delivered down the inclined section 34 to a duct bounded by walls 35, 36 and carried by an air current through a slot (not shown) in the block 21 to join the tobacco passing up the chimney. The slot is so dimensioned and positioned that the stream of shorts is narrower, in the direction normal to the plane of the figure, than the shower of tobacco passing up the chimney and is displaced to one side of the shower whereby that part of the shower containing the shorts is deposited first on the band. Thus shorts are not removed by any subsequent trimming of the tobacco on the band. An arrangement is referred to in which the tobacco is showered by gravity and transferred from the band to a suction wheel or a transfer band before trimming, and in this case the position of the shorts layer is reversed. Reconstituted tobacco may be fed to the tray 27 down a shoot 41, and the overall air flow may be controlled by a flap 22A.
